According to the article, ultrasound can measure brain activity and it can influence brain activity in deeper regions of the brain without invasive probes. Thi

  Stimulation but not recording. “Recording deep neural activity via ultrasound can’t be done through the skull, but it can be done by removing a piece of skull and laying the device on the surface of the brain.”

    There's an obvious ick factor, but when I think about it, it's not really so bad compared to some of the other things we do to our bodies. I can easily imagine getting a chip of skull replaced with a subdermal device, like you might get a tooth replaced or a pacemaker installed.

      To me it's scarier because of the blood-brain barrier and restricted immune response--keeping disease out in the first place is probably more important than usual.

  From the article: > For stimulation, focused ultrasound waves can flexibly target specific regions throughout the brain from outside the skull.

  this is used for treatment of tremors now, fairly successfully.

  > Ultrasound can also be used to estimate neural activity within brain regions by measuring local changes in blood flow via the doppler effect I don't know much about how their stimulation is supposed to work, but I do know quite a lot about ultrasonic imaging and I can tell you this is not going to get you the neural interface that people really want. It's going to get you slightly better "think really hard and the drone flies!" toys.
